Im working on my old High Standard 103 supermatic. It has worn a old Tompson Center pistol scope since the 60's and Im looking to move to a dot sight. I was thinking it would be easy being it already had a mount, and it would be a easy swap... NOT!!! Turns out the mount, and scope is backwards from the norm. The rail is in the scope, and the... Ill use the term "gripping part" is on the base. Is there some adapter to adapt a dot to this style of mount?? Anyone been down this road before?
